Body roundness index (BRI) is a new anthropometric index developed to predict both body fat and the percentage of visceral adipose tissue. Our aim was to investigate whether BRI is superior to traditional anthropometric indices in predicting metabolic syndrome (MetS). This systematic review and meta-analysis was conducted using Pubmed, Scopus and Web of Sciences databases. The estimated pooled areas under curve (AUCs) for BRI predicting MetS was higher than body mass index (BMI), waistto-hip ratio (WHR), body shape index (ABSI) and body adiposity index (BAI), similar to waist circumference (WC) and lower than waist-to-height ratio (WHtR). However, the difference between BRI and BMI, WC and WHtR predicting MetS was statistically non-significant. Similar results were found with the summary receiver operating characteristic curve (AUC-SROC). In addition, the non-Chinese population had pooled AUCs greater than the Chinese population for all indices. Pooled ORs showed that BRI is associated with an increased MetS risk. In conclusion, BRI had good discriminatory power for MetS in adults of both sexes from diverse populations (AUC > 0.7; AUC-SROC>0.7). However, WC and WHtR offer the best performance when screening for MetS, and non-significant differences were found with BRI. In contrast, BRI was superior to BMI, WHR, ABSI and BAI in predicting MetS. K E Y W O R D Santhropometric indices, body roundness index, metabolic syndrome, review
Introduction: The body roundness index (BRI) and a body shape index (ABSI) are novel anthropometric indices established to determine both the amount visceral adipose tissue and body fat. Objective: to investigate whether BRI and ABSI are better predictors of hypertension than body mass index (BMI), waist circumference (WC) or waist-to-height ratio (WHtR). Methods: A systematic search was conducted in the Scopus, PubMed and Web of Science databases up until 31 December 2020. Results: The estimated pooled area under curve [AUC (95% CI)] for BRI [0.67 (0.65–0.70)] for the prediction of hypertension were superior to that of ABSI (0.58 (0.56–0.60)), similar to that of BMI [0.67 (0.64–0.69)], and lower than those WC [0.68 (0.66–0.70)] and WHtR [0.68 (0.66–0.71)]. Nevertheless, the difference of BRI compared to WC and WHtR in the context of predicting hypertension was non-significant. ABSI was significantly lower (p < 0.05) than BRI, BMI, WC and WHtR. Similar findings were observed with the summary receiver operating characteristic curve (AUC-SROC). There were no significant differences between subgroups according to type of population or diagnostic criteria of hypertension. The diagnostic odds ratio (dORs) proved that increased BRI and ABSI were related with an elevated hypertension risk. Conclusions: BRI and ABSI have discriminatory power for hypertension in adult women and men from different populations. Although, WHtR and WC provided the best performance when assessing hypertension, no significant differences were found for BRI. Finally, BRI was significantly better predictor of hypertension than ABSI.
ObjectiveTo quantify the association between the presence and type of drug detected and trauma recidivism in a cohort of patients admitted due to trauma.MethodA cohort study was conducted based on data from a project where the presence of alcohol and other drugs (cannabis, cocaine, amphetamines, methamphetamines, tricyclic antidepressants, barbiturates, opiates and benzodiazepines) was analysed in 1,187 patients aged 16 to 70 years admitted due to trauma. The patients were followed for a period of between 10 to 52 months until June 2016. For this study, the recurrence of injuries from a sample of 929 patients from this cohort was analysed according to their consumption profile. Survival curves were estimated and adjusted Hazard Rate Ratios (aHRR) and adjusted incidence rate ratios (aIRR) were calculated.ResultsThe incidence rate of TR was 10.94 cases per 100 patient-years in the group of patients negative for substances and 27.99 per 100 patient-years in positive patients. The survival curves show very significant differences in cumulative recurrence-free survival between the groups (Log Rank: p<0.001). Both the aHRR and the aIRR estimates show an increased risk of re-injury due to alcohol consumption (aIRR: 2.33 (1.72–3.15), p<0.001), cannabis use (aIRR: 1.87 (1.09–3.20), p = 0.022) and polydrug use (aIRR: 2.34 (1.80–3.04), p<0.001).ConclusionsThe presence of alcohol and/or illicit drugs in these patients doubles the risk of trauma recidivism.
The purpose of this study was to: (a) determine the relationship between quantitative ultrasound (QUS) results and anthropometric, dietary and body composition factors and establish reference ranges for amplitude-dependent speed of sound (Ad-SoS) in the phalanges and broadband ultrasound attenuation (BUA) in the calcaneus of children from Extremadura, Spain, and (b) to present reference curves for this population. Healthy children (n = 245), aged 4-16 years, were included (124 girls and 121 boys). Phalangeal and calcaneal QUS measurements were performed using DBM Sonic Bone Profiler and McCue CUBA Clinical ultrasound devices, respectively. Weight, height and body mass index (BMI) were evaluated by anthropometric methods. Fat percentage, fat mass, lean mass (FFM) and total body water (TBWater) were evaluated by bioelectrical impedance measurements using a Holtain body composition analyzer. Food intake was evaluated by a 7-day food record. A gender analysis revealed that Ad-SoS and BUA parameters increased significantly with age and that both positively correlated with age, weight, height, BMI, FFM and TBWater. For both genders, Ad-SoS showed significant and positive correlations with age, weight, height, BMI, FFM, BUA and TBWater.
Curcumin (diferuloylmethane) is found in the rhizomes of the turmeric plant (Curcuma longa L.) and has been used for centuries as a dietary spice and as a traditional Indian medicine used to treat different conditions. At the cellular level, curcumin modulates important molecular targets: transcription factors, enzymes, cell cycle proteins, cytokines, receptors and cell surface adhesion molecules. Because many of the curcumin targets mentioned above participate in the regulation of bone remodeling, curcumin may affect the skeletal system. Nitric oxide (NO) is a gaseous molecule generated from l-arginine during the catalization of nitric oxide synthase (NOS), and it plays crucial roles in catalization and in the nervous, cardiovascular and immune systems. Human osteoblasts have been shown to express NOS isoforms, and the exact mechanism(s) by which NO regulates bone formation remain unclear. Curcumin has been widely described to inhibit inducible nitric oxide synthase expression and nitric oxide production, at least in part via direct interference in NF-κB activation. In the present study, after exposure of human osteoblast-like cells (MG-63), we have observed that curcumin abrogated inducible NOS expression and decreased NO levels, inhibiting also cell prolifieration. This effect was prevented by the NO donor sodium nitroprusside. Under osteogenic conditions, curcumin also decreased the level of mineralization. Our results indicate that NO plays a role in the osteoblastic profile of MG-63 cells.
The moderate consumption of fish is recommended for a healthy diet and is also a feature of the Mediterranean diet. Fish is a major food group in diets throughout the world, and studies show that fish consumption is associated with a lower risk of a number of conditions. Spain has one of the highest annual per capita consumptions of fish worldwide. As fish is a source of high quality protein; n-3 polyunsaturated fatty acids; vitamins, such as A and D; and minerals, such as selenium, calcium, iodine, magnesium, copper and zinc, nutrients that have positive effects on bone characteristics, it has been proposed that its consumption could improve bone health. In this cross-sectional study, we have investigated the relationship between dietary habits and nutrient intake of 151 Spanish premenopausal women and analyzed the association of fish consumption on bone mass measured by quantitative ultrasound of the phalanges. A higher (P < 0.05) bone mass and vitamin D intake (P < 0.05) was observed in the group with a fish intake of 5–7 servings/week. We conclude that increased fish consumption is helpful in maintaining an adequate bone mass in Spanish premenopausal women.
Elevated selenium intake negatively affects bone mass measurements in postmenopausal women over the age of 51 but only if calcium intake is also less than 800 mg / day. When calcium intake is greater than 800 mg/day, selenium did not appear to affect bone mass.
